NAME

Slackware::Slackget::Network::Connection::FTP - This class encapsulate Net::FTP

VERSION

Version 1.0.0

SYNOPSIS

This class encapsulate Net::FTP, and provide some methods for the treatment of FTP requests.

This class need the following extra CPAN modules :

	- Net::FTP
	- Time::HiRes

    use Slackware::Slackget::Network::Connection::FTP;

    my $foo = Slackware::Slackget::Network::Connection::FTP->new();
    ...

CONSTRUCTOR

new

This class is not designed to be instanciate alone or used alone. You have to use the Slackware::Slackget::Network::Connection.

FUNCTIONS

__test_server

This method test the rapidity of the mirror, by making a new connection to the server and logging in. Be aware of the fact that after testing the connection you will have a new connection (if you were previously connected the previous connection is closed).

my $time = $connection->test_server() ;

_test_current_directory [PRIVATE]

This private methos is used internally each time you require a transfert, for testing if the current directory is the 'path' parameter of the DATA section of the current Connection object.

Do that by sending a PWD command to the server and compare the result with $connection->path.

$ftp->cwd('/any/remote/directory/') unless($connection->_test_current_directory) ;

Due to the fact that this method is private and internal the example is not really explicit, please look at the code for more informations.

__get_file

Download and return a given file.

my $file = $connection->get_file('PACKAGES.TXT') ;

Please note that the Net::FTP module doesn't support a method like that. So, this method is not an encapsulator like the one of HTTP.pm, and use Slackware::Slackget::File to return the content of the downloaded file.

So you'd better to use fetch_file().

__fetch_file

Download and store a given file.

$connection->fetch_file() ; # download the file $connection->file and store it at $config->{common}->{'update-directory'}/$connection->file, this way is not recommended
or
$connection->fetch_file($remote_file) ; # download the file $remote_file and store it at $config->{common}->{'update-directory'}/$connection->file, this way is not recommended
or
$connection->fetch_file('PACKAGES.TXT',"$config->{common}->{'update-directory'}/".$current_specialfilecontainer_object->id."/PACKAGES.TXT") ; # This is the recommended way.
# This is equivalent to : $connection->fetch_file($remote_file,$local_file) ;

This method return a Slackware::Slackget::Status object with the following object declaration :

my $status =  Slackware::Slackget::Status->new(codes => {
	0 => "All goes well.\n",
	1 => "An error occured "
});

__fetch_all

This method fetch all files declare in the "files" parameter of the constructor.

$connection->fetch_all or die "Unable to fetch all files\n";

This method save all files in the $config->{common}->{'update-directory'} directory (so you have to manage yourself the files deletion/replacement problems)

conn

An accessor which return the current Net::FTP connection object
